Lady Aisha (may Allah be pleased with her) said: A bowl of water would be brought to me and I would drink from it while I was menstruating, then the Messenger of Allah (peace and blessings be upon him) would place his blessed mouth on the same spot and drink. And a bone with some meat on it would be brought to me, I would gnaw the meat off with my teeth, then he (peace and blessings be upon him) would place his blessed mouth on the same spot and eat the meat. Then he would instruct me, and I would fasten my lower garment, and he would be intimate with me.
